conix, I have long seen one value in troll presence, in that troll misinformation most often, because we do fact check, leads to some articles et al being here which we might never have seen if not for the troll misadventure. You of course flatter yourself because you see it as only happening with you.
And again the evidence that your echo chamber claim is a myth, a furphy, a strawman is clear due to the ever-presence of a troll or two or three, or more.
Understand it is as sure as Jesus was simply another guy made one with God by man (for most Christians that is, not all) that board upticks are not all about you.
It is common sense that difference of opinion often leads to excess action. The common sense you seem to lack much of the time.
